On December 12, the California Air Resources Board ("ARB") approved stringent operating standards for diesel powered engines.

As part of California's continuing initiative to reduce air pollutants, the ARB approved stringent operating standards for diesel powered engines applicable to approximately 170,000 businesses in nearly all industry sectors in California. The standards require fleet owners to employ best available technology to reduce emissions of particulate matter (PM) and nitrogen oxides (NOx). Trade associations have raised concerns about the costs to retrofit or replace engines or vehicles.
